python - Suddenly, No module named models -

i have project 3 apps, called projects, specimens , tests. working fine until made alter (i don't remember what). after that, django throws importerror: no module named models. can't imagine problem because think have referenced , organized.

this error:

importerror @ / no module named models request method: request url: http://127.0.0.1:8000/ django version: 1.5.5 exception type: importerror exception value: no module named models exception location: /home/david/mysqldb/dev/mysqldb/teams_db/specimens/views.py in <module>, line 11 python executable: /usr/bin/python python version: 2.7.5

and traceback:

/home/david/mysqldb/dev/mysqldb/teams_db/teams_db/urls.py in <module> (r'^specimens/', include('specimens.urls')), ▶ local vars /usr/local/lib/python2.7/dist-packages/django/conf/urls/__init__.py in include urlconf_module = import_module(urlconf_module) ▶ local vars /usr/local/lib/python2.7/dist-packages/django/utils/importlib.py in import_module __import__(name) ▶ local vars /home/david/mysqldb/dev/mysqldb/teams_db/specimens/urls.py in <module> views import new_specimen, list_specimens, info_specimen ▶ local vars /home/david/mysqldb/dev/mysqldb/teams_db/specimens/views.py in <module> tests.models import test ▶ local vars

inside app tests have class test, 1 causing error. function throws error (specimens.views):

and test class in tests.models:

from django.db import models projects.models import project specimens.models import specimen #from operator.models import operator django.core.validators import regexvalidator class test(models.model): ref = models.charfield(max_length=70, unique=true) #name = models.charfield(max_length=70, null=true, blank=true, default='null') project = models.foreignkey(project) specimen = models.foreignkey(specimen) #operator = models.foreignkey(operator) notes = models.textfield(max_length=170, blank=true) description = models.textfield(max_length=170, blank=true) start_date = models.datefield(null=true, blank=true) finish_date = models.datefield(null=true, blank=true) status = models.charfield(max_length=70, blank=true)

would need more information? please, allow me know if necessary. ideas of problem? name tests reserved word??

thanks in advance!!

it import loop, uncertainty import test model anywhere else. don't utilize relative import in view from models import specimen might causing problem. , don't set models in tests.py should used tests , shouldn't need test models tests.
